BOBBIN-SPINDLE AND SUPPORT.

Specification of Letters Patent.

' Patented Nov. 9, 1920.

Application filed October 18, 1919. Serial No. 331,587.

T 0- all whom it may concern Be it known that I, (inonon W. Fnrsnm, a citizen of the United States, and a resident of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented new and useful'lmprovements in Bobbin- Spindles and Supports, of which the following is a specification.

This invention relates to bobbin spindles and their supports and has for its primary object the provision of a simple and effective means whereby the spindle may be readily and easily placed in and removed from operative position.

fin'therobject of the invention is to provide in a device of the above mentioned character a means whereby the spindle may be locked when in an operative position to prevent its being accidentally or otherwise removed during the operation of the machine.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.

in the drawings, forming a part of this specification wherein like numerals are employed to designate like parts throughout the same,

Figure l is a side elevation of the device embodying my invention,

Fig. 2 is a sectional view showing the spindle tilted to enable the same to be removed, and,

Fig. 3 is an elevation taken at right angles to the device shown in Fig. 1, looking in the direction of the arrow.

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 5 indlcates a spindle swing adapted to be suitably secured to the machine or frame thereof by means of a stub-shaft 6. The spindle swing 6 is, because of its peculiar construction, adapted to move horizontally to bring the spindle into contact with a belt ordinarily employed and should it be desired, any conventional type of spring may be employed to retain the spindle in firm contact with the belt. The spindle swing is provided centrally with an opening 7 adapted to receive the lower end of a casing 8 which is provided with a shoulder 9 adapted to be supported upon preferably a felt washer 10 imposed upon the swing 5, the washer being utilized to absorb any vibration caused by the operation of the machine with which the device is adapted to be used. Upon the lower end of the casing or the shank ll thereof there is disposed a coil spring 12 which is supported by a tension adjusting nut 13 adapted for screw-thread adjustment upon the shank 11 as is. apparent. The spring 12 serves as a means for normally retaining the casing 8 in a vertical position in which position the shoulder 9 is retained firmly in engagement with the washer 10 as clearly shown in Figs. 1, 2 and 3. The casing 8 is provided centrally with an elongated opening 14 adapted to receive the tapered end or shank 15 of a spindle 16, which spindle is adapted to receive a bobbin, not shown. The spindle 16 is provided with an enlarged end or housing 17 having a relatively large opening 18 therein which is adapted to receive the casing 8, the casing 8 being spaced an appreciable distance fromthe inner wall of the enlarged end 17 as shown, to permit free rotation of the spindle 16 with respect to the casing 8. The housing 17 at its lower end is provided with an annular flange 19 which is adapted to cooperate with a lug 20 carried by an arm 21, which arm is suitably secured to the swing 5. as clearly shown, to prevent the spindle 16 from being accidentally or otherwise removed during the operation of the machine. Should it be desired, however, to remove the spindle 16 from its cas ing 8 the spindle together with the casing 8 is moved to the position shown in Fig. 2 against the influence of spring 12 whereupon the spindle 16 may be moved upwardly, the flange 19 having, as is apparent, been moved to such a position as to permit it to pass the lug 20.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Havingthus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States is:

1. A device of the character described comprising a spindle swing, a casing sup ported by the swing, a spindle rotatably mounted within the casing, a flange carried by the spindle, an arm carried by the swing,

' the being provided with a lug overlying 52; The combination with a supporting element provided with an opening, of an arm disposed at one side thereof and terminating in an inwardly directed lug, a tubular stand ard disposed in the opening and of a less diameter than the same, a flange formed upon the tubular standard and resting upon the supporting element, a bobbin spindle supported by thetubular standard and including a whorl provided with an annular flange at its lower end, and a coil spring encircling the lower end of the standard and engaging the under face of the supporting element to normally retain the standard in a vertical position where the flanges on the standard. and whorl will be disposed beneath the inwardly disposed lug, the spindle being adapted to be rocked to angular position to dispose of the flange on the same at a point to clear the lug to permit the spindle to be disengaged from the standard.
